TL;DR: In this article, the authors used the CFD-DEM simulation method to study the gas-solid two-phase flow characteristics and erosion characteristics of the gate valve, and the accuracy of the simulation was validated by comparing the simulation and experimental data.

TL;DR: In this article, a high-speed centrifugal pump with a splitter-blade inducer is investigated, and the internal flow with rotating cavitation is numerically simulated and external characteristics are subjected to experimental tests.

TL;DR: In this paper, the effect of the V-angle on valve performance and internal flow properties via experiments and numerical simulations was investigated, and it was shown that an increase in either Vangle or valve opening causes a large pressure fluctuation near the valve outlet, thus leading to a long pressure-stable distance.

TL;DR: In this article, the three-dimensional, steady, incompressible, and turbulent solid-liquid two-phase flows in a low-specific-speed centrifugal pump are numerically simulated and analyzed by using a computational fluid dynamics (CFD) code based on the mixture model of the twophase flow and the RNG k-ε two-equation turbulence model, in which the influences of rotation and curvature are fully taken into account.

TL;DR: In this article, the authors presented the CFD analysis of flow resistance characteristics and the internal flow characteristics of gate valve in a gate valve with different inlet velocities, and concluded that it is not stable before the relative opening degree 2/8.
